If you have misfuelled, National Breakdown will be able to assist with recovery, this is standard on their policies.
However if you have purchased National Breakdown's platinum cover, they will drain the incorrect fuel. If this is not possible at vehicle location, they will arrange and pay for your vehicle, you and up to 7 passengers to be recovered to the nearest suitable garage which can undertake the drainage within 10 miles and refuel the vehicle with up to £10 of fuel of the correct type.
They will also pay all labour costs associated with fitting parts affected by misfuelling as specified by the repairer and agreed by National Breakdown. The maximum amount payable under this policy is £500.00 (inc vat).
